SRK Engineering Thread

So my schools chemistry department cancelled physical chemistry for engineers. I need it, to take reactor analysis and design.

Now I could take the same course for biochemistry and chemistry majors.

Or I could substitute with the what’s called quantum chemistry and spectroscopy. Now I know @tekno virus, said never depend on the prof. But the one teaching the quant section is teaching the physical chemistry section of the class and the average is 49% with no curb. He is going to teach the quant section next semester.

I have a group of acquaintances (2 plus me) who are going to take it. How advisable, and how usefull would a course like this be in real world applications. It can serve as a substitute for physical chemistry, this was confirmed by my advisor.

From what I can gather physical chemistry’s most important lesson is reaction enthalpy, reaction rate, and equilibrium.

I have enough room to take physical chemistry course if it’s that important the following semester.

P. Chem is P. Chem in my opinion. If it’s offered by the chem dept instead of the engr, that’s probably for the best.

@tekno virus, they are all offered by the chem department. All I’m doing is replacing pchem with quantum mechanics and spectroscopy…

Quantum away then

and start reading

That sounds like the world’s biggest wire-wrap tool.

I don’t know how useful it would be for your major, but I’d rather take quantum mechanics over p chem any day of the week.

I’d brush up on your linear algebra if I were you…

Yeah, I’m reading linear algebra done right…diffrent from Goode’s book. But I should be able to manage…it’s already thought me def that would have helped the first round of linear algebra.

If, by wire-WRAP, you’re referring to hair gauge wire and square posts, then no :stuck_out_tongue: not an electrical/electronic tool.

The prof does make a difference. Now, is it hard because it requires skills and takes a lot of practice to get good (like a well-designed video-game)? Or is it hard because the game is set up unnecessarily complicated and the game doesn’t control well and is just poorly designed?

If the prof is putting levels that are difficult to beat, that’s okay, if he’s a douchebag and is just trolling you, then by all means, avoid him.

A lot of this math and engineering stuff is like any video-game. Just know you’re fighting a scripted AI and though while at first you might be stumbling, after a little practice, it becomes routine.

Is anyone here familiar with Xitech pneumatic pump systems?

Wonder what the refund policy’s like on a $150,000 ticket…

20 dollar monthly repayments with 5 dollar increments.

going to write my very first thesis next year

not too sure how it’ll go down. Really scared honestly

For your thesis:
Start early. Work on it every day and it will be done.

If you ever wondered what a 200 million dollar mistake looks like, this is it.

Been offered a project engineer’s job for a software firm. Less money, but in my hometown, so jumping on it.

Anyone here in engineering/IT project management or know any good PM resources that I should read up on?
They run a planning system called “Agile” that I’m not too savvy with.

Agile is pretty much standard these days, basically imagine a year is broken up into 4 releases (just an example). For each release, you break it down into 4 or 5 “iterations.” An iteration is typically 2-3 weeks, but due to math it can be 4 weeks sometimes. Really these numbers are tweakable, a lot of people like to go 1 week, but I digress.

Anyhow, for an iteration you commit to a specific deliverable, and you deliver it during that iteration. You are also doing release planning for what will be released for future releases, and iteration plannings where you are doing meetings once per iteration to plan what will be delivered in the next iteration.

You also have daily standup meetings, which are designed to be literally that: a “stand up” meeting to encourage people to be quick. You spend 1-2 minutes telling everyone what you’re working on, and any issues you are stuck on, and then people can help you figure out how to move forward. Just a quick update, “I am stuck until dev X completes the schema changes” move on.

So whats the upside? Being very “agile” as they say. You spend a week adding a new screen to the application, bam its in. Customers can look at it and give instant feedback, PMs can see whats going on in real time, and most importantly things can shift in importance. Instead of “I spent 3 months adding this feature and now the customer is seeing it for the first time and hates it”, its more “The customer saw the screen and now doesn’t like what they’ve seen; we need to change it.”

The hardest part is breaking your work down into small enough chunks that you can create a deliverable, ESPECIALLY on brand new applications. But you just do stuff like "Create the screen in iteration 1. Iteration 2, add some backend code to handle “load” and “save.” Iteration 3, add more features to the screen. etc.

In short, its supposed to keep a company agile, able to react to a customers needs, and allows you to shift priorities in short order. And the deliverables are simple enough you can jump in and help out when/ where needed. Also, typically when working in agile, half your time is spent on new features, and half your time on bug fixing/meetings. So half a work day is considered a “point” and you rate your deliverables in points. “I can do that feature in 5 points.” then you use a system to track everything, like Rally, and it lists your teams, the iterations, what features you worked on and are planning to work on, and the road map (list of upcoming features and when they’ll be delivered) is constantly changing.

I enjoy it, when you are in bigger companies its needed. Back when I worked at a small, more personal company, it wouldn’t have been needed. This was the kinda place where my boss would come by ,say “I have an idea for X, what do you think?” And we’d come back at the end of the week and be like “Here you go boss, check it out!”

Now its like somebody goes “What do you think of X?” and its like “Sounds good, but you’ll need to run it through the PM and then we can see about adding it to the road map for the future.” But thats just the nature of working in a huge company.

What Pimp Willy said, look up Agile SCRUM lifecycles.
